Description

The Ultimate GPS module you know and love has a glow-up to let it be easily used with any computer, not just microcontrollers! With the built in USB-to-Serial converter, you can now plug-n-play the Ultimate GPS into your computer, laptop, embedded Linux computer, and more. Power and transport data over any micro USB cable, with handy on-board indicator LEDs that let you know fix status and whether data is being received & transmitted.

We believe this is the Ultimate USB GPS module, so we named it that. It's got everything you want and more:

-165 dBm sensitivity, 10 Hz updates, 66 channels

Plug and Play USB with CP2104 USB-to-Serial converter built in.

PPS output on RI (Ring Indicator) serial control pin

USB Micro B connector + two mounting holes

Only 25mA current draw

RTC battery-compatible

Built-in datalogging

Internal patch antenna + u.FL connector for external active antenna

Fix status LED + UART activity LEDs

...all for under $40!

The breakout is built around the MTK3339 chipset, a no-nonsense, high-quality GPS module that can track up to 22 satellites on 66 channels, has an excellent high-sensitivity receiver (-165 dBm tracking!), and a built in antenna. It can do up to 10 location updates a second for high speed, high sensitivity logging or tracking. Power usage is incredibly low, only ~25 mA during navigation.

We added all the extra goodies you could ever want: 4-pin USB breakout for direct-soldering or connection to a USB host, two yellow receive/transmit LEDs let you know when data is being transmitted to or from the GPS module serial interface, a footprint for optional CR1220 coin cell to keep the RTC running and allow warm starts and a tiny bright red LED. The LED blinks at about 1Hz while it's searching for satellites and blinks once every 15 seconds when a fix is found to conserve power. If you want to have an LED on all the time, we also provide the FIX signal out on a pin so you can put an external LED on.

Two features that really stand out about version 3 MTK3339-based module is the external antenna functionality and the the built in data-logging capability. The module has a standard ceramic patch antenna that gives it -165 dBm sensitivity, but when you want to have a bigger antenna, you can snap on any 3V active GPS antenna via the uFL connector. The module will automatically detect the active antenna and switch over! Most GPS antennas use SMA connectors so you may want to pick up one of our uFL to SMA adapters.

NAMEDESCRIPTION

Ordering full reels vs. cut reels

Adafruit NeoPixel Digital RGB LED strips come to us in 4 or 5 meter reels with a 2 or 3-pin JST SM connector on each end and separated power/ground wires as shown in the pic below. If you order a full 4 or 5 meters, you get the full reel with both connectors installed (like the pic below).

If you buy less than a full reel, you'll get a single strip, but it will be a cut piece from a reel which may or may not have a connector on it. If the piece comes from the end of the reel, the connector may be on the output end of the strip!
